Re: Zoom 1JZ Tuners Guide	Wed, 10 December 2003 11:39

My 2 cents worth on this thread and some of the points raised based on first hand experiences over 3 years of owning/modifying a 1J powered JZZ30 Soarer- There's an easy fix for the wastegate/boost creep problem beyond 16 psi - have them bored out to the max ; I'm able to run a steady 20 psi from 3500 to 7000 rpm since my wastegates were modified on my hybrid turbos by GCG. Other than Martin, I'm not aware of any stock turbos flowing 250rwkw or more - anyone heard of anyone else achieving this? Stock injectors max out between 240 and 250rwkw, 440cc injectors max out between 270-280rwkw and 550cc injectors are at 85% duty cycle at 300rwkw in my experience. Oh, all on pump gas, not fancy race fuels. Factory stock manual transmission JZZ30 Soarers run about 130-140rwkw on calibrated Dyno Dynamics dynos - I've personally seen two including my own pushng these numbers - mine produced 134rwkw with only the compliance cat converter altered on the entire car after a complete service replacing all consumables. A factory stock GTR ran 140 odd rwkw immediately after my car on the same dyno. Factory stock Auto JZZ30 Soarers run very similar rwkw figures as well according to the results of numerous ALSC Dyno days despite being burdened with an Auto - either the A340x auto is efficient or the R154 is inefficient if this is the case. Still indiferent about the apparent reliability issues with the difference between "Series I" and Series II" 1J's - yet to see this "factory recall" or observe retrofitting by Toyota Japan when the cars were being serviced, especially on Soarers - perhaps it only applies to JZA70 1J engines?
